Is it taking in raw pixels or reading from game memory? How did they gather data to train for this? (Did Valve give them an API?)

I'm sure they got some kind of official API since this seems to be a partnership between openAI and Valve.

Blizzard's Starcraft did the same thing for their recently announced AI project where Starcraft 2 got an API for the AI developers to work with:

https://developer.valvesoftware.com/wiki/Dota_Bot_Scripting

> Bot scripting in Dota is done via lua scripting. This is done at the server level, so there's no need to do things like examine screen pixels or simulate mouse clicks; instead scripts can query the game state and issue orders directly to units. Scripts have full access to all the entity locations, cooldowns, mana values, etc that a player on that team would expect to. The API is restricted such that scripts can't cheat -- units in FoW can't be queried, commands can't be issued to units the script doesn't control, etc.
